In doing so, Esenboğa confirms its status as one of the world's top 27 environmentally-friendly airports based on ACI's Airport Carbon Accreditation programme.
It is the only airport in Turkey to boast carbon neutral status, which it was first awarded in 2014.
Esenboğa's general manager, Nuray Demirer, says: “TAV Airports has adopted an environmentally and socially-friendly and also a sustainable business model.
"Our goal is to decrease our environmental impacts to the minimum level. As a result of the works performed on energy efficiency, we are glad to sustain our carbon neutral airport title since 2014."
According to TAV, Esenboğa Airport's energy efficiency efforts have included the installation of automatic lighting controls, using LED fixtures and the utilisation of a trigeneration plant producing power, heating and cooling energy from natural gas.
The gateway handled 12.3 million passengers and approximately 88,000 flights in 2015.
